Incidence of postintubation hemodynamic instability associated with emergent intubations performed outside the operating room: a systematic review.

Objective: Hemodynamic instability following emergent endotracheal intubation (EETI) is a potentially life-threatening adverse event. The objectives of this systematic literature review were to document the incidence of postintubation hemodynamic instability (PIHI), to determine the definitions for PIHI used in the available literature, and to examine factors associated with PIHI in adult patients who require EETI.

Data Source: Articles published in Medline (1966-August 2012).

Tiotropium in combination with placebo, salmeterol, or fluticasone-salmeterol for treatment of chronic obstructive pulmonary disease: a randomized trial.

Background: Treatment of moderate or severe chronic obstructive pulmonary disease (COPD) with combinations of inhaled corticosteroids, long-acting beta-agonists, and long-acting anticholinergic bronchodilators is common but unstudied.

Objective: To determine whether combining tiotropium with salmeterol or fluticasone-salmeterol improves clinical outcomes in adults with moderate to severe COPD compared with tiotropium alone.

Design: Randomized, double-blind, placebo-controlled trial conducted from October 2003 to January 2006.
